用java画国际象棋棋盘

        用java画了一个国际象棋的棋盘，不难，还是挺好玩的。

package com.test;

import java.awt.BorderLayout;
import java.awt.Color;
import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.UIManager;

public class Chess extends JFrame {

    
	private static final long serialVersionUID = 1L;
	
	JPanel jp=new JPanel();
        
    public Chess(int gridSize){
    	
    	//这句忘加可不行
    	jp.setLayout(null);
    	for(int i=0;i<8;i++)
    		for(int j=0;j<8;j++)
    		{
    			Color color=Color.white;
    			JLabel label=new JLabel();
    	    	label.setSize(gridSize, gridSize);
    	    	label.setLocation(i*gridSize, j*gridSize);
    	    	if((i+j)%2==0)
    	    		 color=Color.black;
    	    	
    	    	label.setOpaque(true);
    	    	label.setBackground(color);
    	    	//设置边界线为黑色
    	    	label.setBorder(BorderFactory.createLineBorder(Color.black));
    	    	jp.add(label);
    	    	//Jpanel加在JFrame上
    	    	add(jp, BorderLayout.CENTER);
    		}
    }

	public static void main(String[] args) {

		try {
			//用当前系统的窗口风格
			UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());  
		}catch (Exception e) {
			e.printStackTrace();
		}
         Chess chessBord=new Chess(100);
         chessBord.setSize(810,835);
         //加上这句可以让窗口居中
         chessBord.setLocationRelativeTo(null);
         chessBord.setVisible(true);
         chessBord.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        
	}
}
